C# Sharp Basic Algorithm Exercises: Compare two given strings and return the number of the positions where they contain the same length 2 substring


C# Sharp Basic Algorithm: Exercise-35 with Solution

Write a C# Sharp program to compare two given strings and return the number of the positions where they contain the same length 2 substring.

Sample Solution:-

C# Sharp Code:

using System;
using System.Linq;

namespace exercises
{
   class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(test("abcdefgh", "abijsklm"));
            Console.WriteLine(test("abcde", "osuefrcd"));
            Console.WriteLine(test("pqrstuvwx", "pqkdiewx"));
            Console.ReadLine();
        }

        public static int test(string str1, string str2)
        {
            var ctr = 0;
            for (var i = 0; i < str1.Length-1; i++)
            {
                var firstString = str1.Substring(i, 2);
                for (var j = 0; j < str2.Length-1; j++)
                {
                    var secondString = str2.Substring(j, 2);
                    if (firstString.Equals(secondString)) 
                    ctr++;
                }
            }
            return ctr;
        }
    }
}

Sample Output:

1
1
2

Previous: Write a C# Sharp program to check whether the sequence of numbers 1, 2, 3 appears in a given array of integers somewhere.
Next: Write a C# Sharp program to create a new string from a give string where a specified character have been removed except starting and ending position of the given string.
